GAR WHEEL...

SPECIFICATION forming part of Letters Patent No. 387,209, dated August 7, 18488.

A Application filed September 9, 1886. Serial No. 213.051. (No model.)

To all whom it may concern;

Be it known that I, WILLIAM HENRY BROWN, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Railway-Wheels, of which the following is a specification, reference being bad to the accompanying drawings.

The invention relates to railwaywheels which are composed principally of two disks or circular plates of wrought-iron or steel, one of which forms one side or face of the wheel, together with the whole of the flange and tread I 5 and a portion of the hub,and the other of which forms the other side or face and another portion of the hub.

The improvement consists in the novel construction of these plates or wheelsections and the novel combination with them of a hubbushing and an interposed filling of wood, paper, or other material, as hereinafter described and claimed.

Figure l in the accompanying drawings mp 2 resents an axial section of that one of the said disks, plates, or wheel-sections which constitutes one side or face, the tread, the flange, and a portion of the hub of a wheel constructed according to my invention. Fig. Zrepresents an axial section of the complete wheel. Fig. 3 is a side view corresponding with Fig. 2. Fig. 4 is a sectional diagram illustrating the method of producing the disk or wheel-section shown in Fig 1.

Similar letters of reference designate corresponding parts in the several figures.

The disk or wheel-section shown in Fig. 1 is made from a flat disk or circular plate of steel or wrought-iron of sufficiently larger di- 0 ameter than the intended diameter of the wheel outside of the flange. This disk is heated, and then, by means of a plunger and die or other suitable means, has its edges turned in to bring it to the cup or shallow cylindrical form shown in Fig. 4c, the external diameter of the rim or turned-in part 0 being equal to the intended external diameter of the flange d. A hole is then punched in the center of the disk or plate, and the metal is turned inward around the said hole, as indicated in Fig. 4 by dotted outline, by means ofa plunger and die or other suitable means to form an internal tubular projection, 1), half thelength of the hub. The next and final operation is to contract the rim 0, as indicated in dotted out line in Fig. 4, to produce the tread a, such contraction extending to within a suitable distance of the disk a to produce the doubled flange d. This contraction of the rim may be performed by pressing in a'die or by rolling or spinning while the metal is in a sufficiently heated state. The other disk or wheel-section, cf, of the wheel (shownin Figs. 2 and 3) consists of a disk or circular plate, 6, of wrought-iron or steel, in the central portion of which is a hole, from which the metal is turned inward to form an internal tubular projection, f, which corresponds with the hub portion b of the other section and forms the other half of the length of the hub. The outer circumference of the disk 6 fits snugly within the interior of the rim or tread portion 0 comprised in the other wheel-section.

The two wheel-sections a b c d and ef have inserted tightly within their cor-respondinghub portionsb andf a lining tube or bush, g. This tube may be secured to one of the sections by riveting, or may be secured in either or both sections by shrinking the portions bf upon it, or may be screwed into both sections. When a long hub is desired, this tube or bush 9 may be longer than the hub portions 1) andf.

The cavity formed between the disks a e around the hub portions b j and within the rim or tread a is filled in with wood, paper, or any other light but solid material, and-is represented in Fig. 2 as filled with wood or paperboard in the form of disks 'i t, which are compressed tightly between the disks a e by means of screw bolts h h, which pass through both disks.

A wheel thus constructed has the merit of lightness in proportion to its strength. It is elastic and not likely to be broken either by shocks or by expansion and contraction, and is almost noiseless. Such a wheel is, moreover, capable of being produced very cheaply.

What I claim as my invention, and desire both of the said tubular projections and the IO to secure by Letters Patent, isclamping-bolts clamping the filling between The combination of the two principal wheelthe disks a c, all substantially as herein desections a b c d and e f the filling i the bushscribed.
